Mas primeiro, vamos verificar alguns pequenos conceitos.

## Está com pressa?

Se você não se importa com qualquer um desses termos e só precisa adicionar segurança com autenticação baseada em usuário e senha _agora_, pule para os próximos capítulos.

## OAuth2

OAuth2 é uma especificação que define várias formas para lidar com autenticação e autorização.

Ela é bastante extensiva na especificação e cobre casos de uso muito complexos.

    @Test
    @DisplayName("Should handle null delimiter by inserting 'null' string")
    void testJoinWithNullDelimiter() {

                // Return unsorted list to test sorting
                return List.of("Zebra", "Apple", "Banana").stream().sorted().collect(java.util.stream.Collectors.toList());
            }
        };

        assertEquals(3, names.size());
        assertEquals("Apple", names.get(0));

## Common Use Cases

### E-commerce Search

```java
// Product search suggestions
SuggestItem product = new SuggestItem(
    new String[]{"iPhone 15 Pro", "Apple iPhone 15 Pro"},
    new String[][]{{"iphone"}, {"apple", "phone"}},
    1.5f,                               // boost popular products
    new String[]{"electronics", "mobile"},
    new String[]{"customer"},
    SuggestItem.Kind.DOCUMENT
);
